Question

question 1 - 30
what would most likely happen to the motion of the planets without the force of gravity from the sun?
the planets would drift away from the sun into outer space.
the planets would slow down, eventually stopping all motion
the planets would continue to move in large circles or ellipses
the planets would gradually make smaller and smaller circles or ellipses

Explanation:

According to Newton's first - law of motion, an object in motion will stay in motion with a constant velocity in a straight line unless acted upon by an external force. The Sun's gravitational force keeps the planets in their orbits. Without this force, there would be no centripetal force to keep them in orbit around the Sun, so they would move in a straight - line path away from the Sun into outer space.

Answer:

The planets would drift away from the Sun into outer space.
